IMPROVEMENT l IN HOISIfING'G-RAPPL ES.

The Schedule referred to in these Letters Patent and making part of the sme.

To all lwhom it amig/ concern Be it known that I, JOHN A. BURGEss, of Plymouth, in the county of Plymouth and State of Massachusetts, have invented a new and usefullmprovement in Hoisting-Grapple; and I do hereby declare that the following is a full, clear, and exact description thereof, which vwill enable others skilled in the art' to make and use the same, reference heilig had to the accompanying drawing forming part of 'this specification.

The object of this invention is to facilitate the operation of hoisting barrels,'containing fish or other material or substance, having but one hea-d, designed more especially for use in shing vessels for -hoisting and lowering ishlwhich arensually packed in open barrels) into the holds of the vessel; andl It consists in 4a bail,to the eyes of which are loosely attached two semicircnlar grappling-jaws, which are made to span the barrel,l so that the barrel may be hoisted thereby, as hereinafter more fully described.

I n the accompanying drawing- Figure l represents the grapple, as when in use, or attached to a barrel, the latter being seen in dott-ed lines.

Figure 2 is a top view of the grapple.

Similar letters of reference indicate corresponding.

parts. v

A is the bail, which has an eye, B, at each end, and a central eye,-G, to which the hoisting-hookis attached, as seen in g. 1.

'D D are` the grappling-jaws, which arei'semic'il'cular in form, the ends of which are attached, by eyes E,

'. to the eyes C of the bail,. so that thegrapples D D hang loosely on the bail.

Each ofthe grapples4 D D are provided with one or A Inore'teet-h, Il, which, when the grapple is applied to a barrel, as seenin tig. 1, penetrate the wood of the barrelas the weight is brought upon them in lifting. This lprevents the grapples from slipping off the barrel. The adhesion thus caused is s niiicient to raise any desired weight.

For hoisting barrels with but a 'single head, thisV grapple is invaluable, especially on board of fishing vessels. l

Having t-hs described my invention, I claim asnew and desire to secure by Letters The hail A, vand the grappling-jaws D D, oonstrncted and arranged to operate in combination, substantially as land for the purposes described.
